sap is performing slow

[Former Member]

Sap is performing slow. It is an IDES ECC 6.0 system on windows2008(VMWARE) /MSSQL2005. transactional log is empty. no muc buffreing. 4gB RAM .

No dumps. No jobs(in relation to slowness). From times to times it performs well but have no idea why?

Whaqt check to perform? I agree RAM should be added (how much for a course of e.g.10 people)

Hi,

Even though the Available RAM size is not so enough as well as recommended, First I would analyze the Swap ratios of the following Buffers in ST02.

1. Repository buffers (nametab buffers)

2. Table buffers

3. Program buffers

4. Roll and page file buffers

5. SAPgui buffers

If the above Buffers are showing more swaps than expected, then do the needful according to available memory.

-->> Also look at the CPU & Memory Bottleneck issue, Memory Page-in/Page-out ratios in ST06.

-->> Also, I would reduce the no. of Dialogue/Background work processes for the same.

-->> Also check the System event-log to get info. regarding the other possible factors.

4 GB is really VERY few memory. Keep in mind:

- operating system needs RAM

- database needs RAM

- on 64bit systems a Java Addin allocates 2 GB RAM fixed

- the SAP system allocates RAM

If the system is mainly busy with swapping (check ST06 - Detail analysis - memory) it's just slow.

I would use at least 8 GB RAM (on 64bit).
